I installed 10.8.2 using instructions in http://lifehacker.com/5938332/how-to-run-mac-os-x-on-any-windows-pc-using-virtualbox?post=52242911 as a VirtualBox virtual machine.
Now it boots without the HackBoot.iso, but when I try playing youtube video it blinks and audio keeps stopping and starting again.
What could be wrong?
